Cisplatin and Docetaxel With or Without Radiation Therapy in Treating Patients Who Are Undergoing Surgery for Newly Diagnosed Stage III Non-Small Cell Lung Cancer

DISEASE CHARACTERISTICS:

• Histologically or cytologically confirmed primary non-small cell lung cancer (NSCLC)*, including any of the following cellular types:

  • Adenocarcinoma
  • Squamous cell carcinoma
  • Large cell carcinoma
  • Non-lobar and non-diffuse bronchoalveolar cell carcinoma
  • NSCLC not otherwise specified NOTE: *Diagnosed within the past 3 months; diagnosis by mediastinal nodal biopsy or needle aspiration allowed provided a distinct lung primary (separate from the nodes) is clearly evident on CT scan

• Stage IIIA disease

  • T1-T3 disease

    • If pleural effusion is present, must meet ≥ 1 of the following criteria to exclude T4 disease:

      • Pleural effusion cytologically negative by thoracentesis
      • Documented absence of pleural metastases and pleural effusion cytologically negative by thoracoscopy (for patients with pleural effusion on CT scan [but not on chest x-ray] that is deemed too small to tap safely under either CT scan or ultrasound guidance)

  • Confirmed positive ipsilateral mediastinal lymph node(s) (N2 disease)**, with or without positive ipsilateral hilar nodes, by mediastinoscopy, mediastinotomy, endoscopic ultrasound-guided transesophageal biopsy, thoracotomy, video-assisted thoracoscopy, Wang needles, or fine needle aspiration under bronchoscopic or CT guidance

    • N2 nodes must be separate from primary tumor by CT scan or surgical exploration AND maximum diameter ≤ 3.0 cm
    • Mediastinoscopy OR other means of mediastinal lymph node biopsy required (regardless of the primary tumor site) for patients with subcarinal lymphadenopathy by size criteria or by positron emission tomography (PET) scan
    • If the lymph nodes in the contralateral mediastinum and neck are visible by contrast CT scan of the chest AND are ≥ 1.0 cm OR if contralateral involvement is suggested by PET scan, lymph nodes must be confirmed negative by one of the above diagnostic procedures AND N3 status must be confirmed negative by histology or cytology
    • No palpable lymph nodes in the supraclavicular areas or higher in the neck unless proven benign by excisional biopsy

    • A nodal biopsy or needle aspiration may be omitted provided all of the following criteria are true:

      • Paralyzed left true vocal cord by bronchoscopy or indirect laryngoscopy
      • Nodes visible in the aortopulmonary window (level 5) region on CT scan
      • Distinct primary tumor (separate from the nodes) is visible by CT scan
      • No evidence of subcarinal nodal involvement by CT scan NOTE: **PET scan positivity is not sufficient to establish N2 nodal status
• Measurable disease by chest x-ray and/or contrast-enhanced CT scan

• Candidate for surgery

  • Resectable disease
• No distant metastases, including other ipsilateral or contralateral parenchymal lesions or liver or adrenal metastases, by history or physical examination, fludeoxyglucose F 18 PET scan, MRI or CT scan of the brain, chest x-ray and/or CT scan of the lungs and upper abdomen
